Building KDE4 From Source (Linux From Scratch requirements)
NOTE: This page was a totally out of date. The instructions in the BLFS book are now what I would recommend you use. So, the old material has been deleted and will be replaced with notes on going beyond the BLFS book organized by minor KDE release number starting with KDE-4.10

KDE-4.10.x

What to build

I will presume that you are at: Further KDE packages

The first thing to note is that KDE is being broken up into individual packages. At least part of it is. BLFS from scratch hasn't quite kept up with that. So, you will find that there are no monolithic packages for:

Kdeaccessability

Kdeartwork

Kdeedu

Kdegames

Kdegraphics

Kdemultimedia

Kdeutils

So, your are going to be installing individual packages based on what you want.
